Sinful San Francisco is a pretty popular polish. I never picked it up until a little while ago and I have to say it is pretty...but not uncommon. I will have to swatch and compare but I think I have a dupe to it in my collection.

This is three coats + Essie Matte About You + Konad (must look up plate...) done with China Glaze Millenium. And I will say again how FANTASTIC the China Glaze metallics are for Konad. I will be picking the rest of them up for this reason alone :)
